Application filed-March 3.1, 192a. Serial No. 355,044.

To (ZZZ 1071 am it may concern:

Be it known that'l, HERBERT 3 is'rINGs, a citizen of the UnitedS-tates,residing at Rochester, in the county of ldonroe -and State of How Yorkhave invented certainnew and useful Improvements in Oil Gauges,

of which the following is a. specification.

The object of this invention'is to provide a new and improved form ofoil gauge,

This and other objects of the invention will be fully illustrated in thedrawings,

described in the specification and pointed "the cams formed in the sideof the cap.

In the drawings, like'reference numerals indicate like parts. i i

In the drawin s, reference numeral 1 indicates the float of the gaugeguided by the guide rods 2 and 3 which are joined together by the yokeat the bottom. The

float is grooved on the sides as indicated at,

5 and (S and is bound around the opening by a strap 7, which strap has aforked end at 8 that en ges with the guide 3. The tongue which struckdown from'the fork engages 'h the float at 9 and the other end of thestrap en yes with the float at 10. The float and strap are perforated toengage with the s1 g uzue rod ll, which rod is twisted spirally on tselfso that as the float rises and tails thereon, the square rod 11 will heturned thereby, the float being held against rotation by the guide rods2 and 3, The upper ends of the 'uide rods are rigidly fastened in thecover 12 which is cup shaped in the middle, the depression being roundin outline. In this depression the guide rods are fastened. end turnedround as indicated at 13and is mounted to rotate in the yoke 4 in thebottom. At the top it passes 'thru the cover 12 in which it mounted torotate and on its upper end carries the pointer let which poinis at thevarious marks on the dial for i The square rod 11 has its lower thepurpose of indicatingthc extent to: which thetank is fuli or empty thefloat rises or falls in the tank. The margin of the -cup :12 issurrounded bytheweb loiwhichj sjoctagonal in shape and lr'onifwhich-extends ikiwnwardly the flange 16-which is also oc- J.

cover is carried the reading dial 17 a space a1 "in shape sothat awrench can he appliedthereto for the purpose of turning itjin the cupshaped depression of the mg ring 18, around glass plate'19, a washer 720 and a lockin r rin b which the )arts 7 b b 7 i are'held in place anda water or oil tight oint 18 secured; Thesldes of the-cup shaped portionof the cover are struck out at 1ntervals about 120 apart to form camshaped lugs 22, each of which has a locking depression 23 therein; Thedepressions 23 in the cam surfaces of the cam lugs 22 form shoulders 23Anear the end of these cam surfaces as illustrated in'Flgures 1A and 5.For the purpose of fastening the oil gauge in the tank, I provide theflanged collar 30,

in" which 31- indioates the collar and'32 indicates the outsldefiangehaving openings therein by which it is fastened to the tank 7 by screwsand rivets. Inside of the collar -is the inside flange 33 whichisrecessed at 345, 35 and 36 to receive the lugs struck up in thecup'shaped part of the cap. WVhen the flanged collar 30 is fastenedon'the tank the float'and guides are passed thru' the opening in thecollar and the lugs22 pass down l11tOlt l161 IGC6SS6S 34:, 35 and 36until the cams on thejlugs 22 'can engage under thein'ner'flange 33 atthese recesses.

turning the cap on its vertical axis tl 1e inside flange is forced up onthe cams until a further movement of it is arrestedby the shoulder 23Aand this locks it sufficiently against movement as illustrated in Figure1A. [The cap is moved to this position by putting a wrenchrthereon andforcibly turning it and can be moved back to its starting point in thesame manner when it is desired to remove the gauge.

' I claim:

1. In a gauge, the combination of a flanged collar having a series ofrecesses on the in side thereof, a head having a cup shaped depressioncapable of engaging in said collar, lugs formed on the outside oftheside of said cup shaped depression, said lugs having cam shaped surfaceson the top thereof said lugs bemg capableofpassmg llO into said recessesand engaging underthe QCSSQS.
